Indeed.

Also true...

I do wonder if the correct fix in the longer term would be to deal only 
in "cmdline" internally but to add a "user friendliness" layer on the top 
which will take individual parameters and use them to build the correct sort 
of command line for the particular guest you're running...  Either a "wizard" 
of some sort, or something in the tools.

In the meantime, I don't know...  We should document the use of the extra= 
parameter a bit better.  Maybe we could also introduce a new "cmdline" 
variable so that folks don't get confused between the two styles of setting 
up a VM...

Thanks for the feedback!

Cheers!
